Silicon.com recently published this case study about how Monarch Airlines set up Google Custom Search Business Edition on www.flymonarch.com to enable better customer self-service and reduce the number of customer support inquiries. As a result of deploying the search engine – which only costs $100 per year - Monarch saw a 30% decrease in the number of customer support inquiries. The case study cites a number of the great benefits of deploying Custom Search: speed, relevance, and customizability. Monarch also uses Google Analytics to understand how their site's visitors navigate.
